Title: Method and device for displaying image
Inventor: OKUI MASATO
IPC: H04N13/02
Filed: 1996-12-04
Abstract: PROBLEM TO BE SOLVED: To make a three-dimensional(3D) image displayed by both image signals for the left eye and the right eye into a 2D image projected on a virtual display screen by providing horizontal shift mutually between both signals. SOLUTION: An input image signal is converted by a geometrical converting circuit and the image signals for the right eye and the left eye are generated and displayed as the 3D image on a two eye 3D image display device. The geometrical converting circuit transforms the coordinate of 2D input image signal so as to display it on any arbitrary virtual display screen, and image information Q at the position of intra-screen coordinate (x, y) is displayed while being transformed to the position of Qr(x+Δx, y) in respect to the image for the right eye and transformed to the position of Q1(x-Δx, y) in respect to the image for the left eye respectively. Since an observer observes the coordinate transformed image with the left and the right eyes respectively, there is a visual effect that the input 2D image seems displayed on a curved image display screen for the observer.

Filed: 1987-12-23
Abstract: PURPOSE:To obtain the lightweight photographic lens whose various aberrations are compensated excellently by forming at least one of 2nd, 3rd and 4th lenses of resin and satisfying a specific condition. CONSTITUTION:The condition of 1.04<N1/N4<1.25 (where N1 is the refractive index of a 1st lens and N4 is the refractive index of the 4th lens) prescribes a refractive index ratio for compensating the 1st lens L1 which is a positive lens by using a high refractive index according to image plane characteristics which are easy to deteriorate because of the use of a low-refractive-index type as the 4th lens L4, and the overall length increases when a lower limit is exceeded. An upper limit is prescribed by using resin or low-refractive-index glass for the 4th lens L4 and when the upper limit is exceeded, the spherical aberration becomes over.

Title: Noninvasive blood pressure measurement system
Inventor: UGAWA SADAJI
IPC: A61B5/1455
Filed: 1992-12-07
Abstract: PURPOSE:To eliminate an error due to a vibration and body motion by selecting an effective pulse wave signal on the basis of degree of oxygen saturation on the DC component of a received optical signal, and calculating a blood pressure value from the amplitude of the pulse wave signal and cuff pressure. CONSTITUTION:Light is emitted in order from the diodes 5a and 5b of a luminous section 5 to a living body tissue 7 in non-pressurized state, and a transmitted light amount is detected with a light receiving section 6A. The transmitted light is separated into a DC component and a pulse wave component for each wavelength of lambda1 and lambda2. CPU 1 measures the degree of oxygen saturation at every pulse and calculates the mean value thereof. Furthermore, the CPU 1 multiplies the mean value by an allowance value to calculate an allowable dispersion range. When a calculated value is judged to be outside the allowable dispersion range, due to a noise effect attributable to a vibration and body motion at the pressure rise process of a cuff 4, a pulse wave component detected during the process, or a photoelectric capacity pulse wave signal is made null. A testee's mean blood pressure value, highest pressure value and lowest blood pressure value are respectively calculated from the amplitudes of effective photoelectric capacity pulse wave signals effective at each pulse and cuff pressure values. As a result, a substantial noise component outside the allowable range can be eliminated, and measurements can be undertaken with high reliability.
